I'm so glad you and the kids are safe. I'd suggest, unless the police put you in touch with one already, connecting with a domestic violence advocate. They have a lot of support and resources to help with the aftermath of this, and also to help you going forward. I hope that your husband gets sober--for everyone's sake, including his own--but the violence is a separate issue, and I hope the court requires him to undergo a batterers' intervention program, as well.
Hugs, good job, mom!
